Sometimes, through client or engineer preference, primary aggregates are specified and recycled materials are deemed an unacceptable alternative. In these circumstances, London Rock can offer primary aggregates and stone to Highway works specification.

The primary materials offered by us are as follows:

• Limestone
• Granite
• Sand and gravel both land-based and marine
• Ragstone
• Sandstone
• Hoggin
• Chalk

Due to the specific geology in areas of the United Kingdom different types of hard stone are more ecconomically viable in some areas than others. London Rock can advise you of which materials naturally occur in which areas.

We also source and supply specified ornamental landscape and decorative stone and sand for the Landscape Industry.
